I am using a password e-mailed to me to log in. How, stroke by stroke, can I change it to something I can remember?My 3205B scope looses it's USB link after a while, and I have to reboot the computer before I can bring it up again.The pilot light is always red. On a four channel PicoScope, I have used, the pilot turns green when all is well.

When logged in, on top of page, just above the line “It is currently Fri …”, on the left hand side, below the “Board Index” there is a link “User Control Panel”.It may depend on your browser, but with my OS X + Safari it is nearly invisible because half of the line is missing.

OK, the USB connection crashes.If you have to reset the computer I’d assume its the computer (don’t lough ! ).Usually you’d disconnect the USB, close (or force quit) the SW and connect USB again.So the first question would be which computer and which OS do you use?

It seems to me PicoScopes are a bit critical in terms of USB power and spikes on USB data lines.

Always and only use the blue original Pico USB cable from PC to the scope.

Don’t use any USB hub in between.Try a different USB port or your machine, some are better, sounds strange but try!

I have a 2205 and the red LED is always on when it is powered up, it is off when the scope is SW connected (driver) and idle, and flashes / is on on data acquisition - but always red.

The next question would be regarding the “after a while”, using the scope, changing (GND) probes, switching ranges, or computer and scope in idle, after sleep mode, and so on ...
